circumference = π x diameter ⇒ diameter = circumference ÷ π = 12 cm ÷ π ~= 3.8 cm
C = d x pi 37.68 / 3.14 = d your diameter is 12cm
The circumference of a circle is C = 2πr, where C is circumference, π is pi (3.14), and r is radius. C = 2 x 3.14 x 12cm = 75cm = 75/1 cm
75.3984
Use Pythagoras' theorum a2 = b2 + c2 a2 = (9x9) + (12x12) 225 = 81 + 144 Ö225 = 15cm > 14cm. answer NO.
The circumference of a circle if the diameter is 12cm is 37.7cm
12pi cm
12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
Using 3.14 as Pi the area of circle is: 113.03999999999999
The diameter of circle A is 12cm so its radius must be 6cm.
perimeter of a circle = circumference = pi x diameter perimeter = 3.1416 x 12 = 37.7 cm
circumference = π x diameter ⇒ diameter = circumference ÷ π = 12 cm ÷ π ~= 3.8 cm
Circumference = pi x diameter. So the circumference of a circle with diameter 12 cm = pi x 12 = 37.7 cm (1 decimal place.)
C = d x pi 37.68 / 3.14 = d your diameter is 12cm
The radius of a circle is the distance from the centre to the edge. The diameter is the distance right across the circle through the centre. So the diameter of a circle is always twice its radius. So if the radius of a circular CD is 6cm, the diameter is twice this - 12cm.
